This article presents the research on the use of new sodium silicate-, guanidine-, and sodium hydrogen phosphate-based compounds to impart the
fire-retardant properties to cellulosic textile materials. We studied the influence of the concentration of the initial components, temperature, and heat treatment time on the fire resistance of the fabric, where the fire-retardant properties of the cotton fabric were changed in three heat treatment modes: at 100°C, 120°C and 140°C. Then the optimal conditions for the treatment of cellulosic materials by the proposed sodium silicate-, guanidine-, and sodium hydrogen phosphate-based compounds were established. With an increase in the concentration of the fire-protectiveness,
and the temperature of the heat treatment, as well as the loss of material strength, and its breaking load, the appearance of the fabric changed only slightly. The proposed compounds allow achieving higher fire-retardant properties. The treatment can be carried out on standard equipment of finishing enterprises without the stage of high-temperature fixation.
Keywords: cellulosic materials, fire retardant properties, sodium hydrogen phosphate, sodium silicate, guanidine, sol-gel technology.
